STEAM-HEATER.

:EiPECIPICATION forming part of Letters Patent No. 303,912, dated August 19, 1884.

Application filed February 16, 1834. (No model.)

Total/l whom it may concern:

Be it known that I, JEROME L. Borne, a citizen of the United States, residing at Go lumbia, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Heaters, of which the following is a description.

Figure 1 is a perspective view, and Fig. 2 a vertical section of my improved steam-heater.

My invention relates to that class of steamheaters which are employed for generating and circulating a body of steam through asys tern of pipes in continuous circuit for heating coils or radiators in the severalrooms of a building. v v

My invention relates more particularly to that class of steam-heaters which have a cen tral magazine above the fire-pot, with an annular boiler around the latter; and it consists in the peculiar construction of the castings forming the bottom of the heater, in the peculiar construction and arrangement of an annular superheating steam-chamber located in the hot-air and smoke space in the upper part of the heater, and in the disposition of the ened, by bolts 0, a ring, S, with downwardlyproj ect-ingfingers forming the lower portion of the fire-pot. Against the flange 1) rests the lower edges of the fire-pot wall T and the boiler-shell U, which latteris made conical at its lower end and cylindrical above. It will be seen, therefore, that the ring-plate R and ring S are securely fastened together and rest loosely upon the base Q,whose upper edgefits between the ring S and the pendent flange a.

In the upper portion of the base Q are openings M, with sliding doors,through which access may be had. to the grate with a poker all around the heater to shake down the ashes and remove clinker-s.

V is the crown-sheet of the boiler, between which and the top of the fire-pot there are a number of tubes, V, for the passage of the products of combustion, and X is the inside wall of the boiler, which connects the crown sheet and fire-box.

Z is the top plate of the heatcr,which closes in the smoke-space, and sustains the central magazine, Y, through which coal is fed to the fire-pot. This magazine is loosely supported by a lip or flange at its upper edge, so that it can be easily removed, and in diameter it is somewhat less than that of the wall X, so as to leave an annular smoke-flue between.

Between the crown-sheet V and the top cover, Z, there is an annular space in which I locate an annular stealn-superheating chambor, A, which is supported upon legs a on the crown-sheet, and is connected with the steam-space of the boiler by the elbowed pipe A", and from which the steam issues through pipe K in its passage to the radiators. This annular chamber is composed of two ringshaped sections of metal, one much wider than the other, and having its edges bent up to contact with the edges of the smaller section, and bolted thereto, as shown. Through this annular superheating-chamber there are also short tube-sections V, which are arranged to register with thetubes or fines V below. By means of this annular superheater the steam is not so wet as it passes to the radiators, the condensation in the latter is reduced, and a more rapid circulation of steam and better heating effect are obtained.

From the steam-pipe Kthere rises a steanr gage, A, and safety-valve G. A pipe, E, also extends from the steam-pipe K, and supports the regulator B, which has within itafiexible diaphragm, B, of soft rubber or other "material. This pipe E, however, does not act as a conduit for steam, but is a blanked pipe plugged to prevent passage of steam, and hav- 5 IOC) H is the return-water pipe, by which the condensed water or cooled steam returns from the radiators to the boiler, and I is apipe com municating with the boiler below the waterline, and also with the under side of the dia phragm in the regulator.

F F F are valves in the pipes G H Lwhich pipes have at their lower end a treble-jointed connection, so that it is only necessary to tap the boiler at one point for all three of these pipes.

P is a damper in the smoke-pipe, and N is a draft-damper for the fire-pot, which are respectively connected by chains 0 O to the opposite ends of a lever connected by a rod or stem with the diaphragm of the regulator. The arrangement of these parts is such that when the fire burns too freely the increased pressure on the diaphragm moves the lever and closes draft-damper N, and opens smokepipe damperl until the heat and pressure are sufficiently reduced, and when this takes place the diaphragm, in falling, opens again the draft-damper N, and closes smokepipe damper P, thus securing an automatic and exact regulation of heat and pressure and the most economic use of fuel.

Having thus described my invention, what I claim as new is- 1. The combination, with the supporting base Q, of the ring-plate R,having downwardlyprojecting flange a on the outside, and upwardly-projecting flange b on the inside, the

described.

2. The combination, with the steam-heater, having central magazine, Y, boiler U V X, and an annular smoke-space'above its annular boiler, of the annular superheating-chamber A, composed of two ring-shaped pieces of metal of different widths riveted together, as shown, the short flue-sections W, and legs a, as and for the purpose described.

3. The water-supply pipe G, water-return pipe H, and regulator-pipe I, having a triple connection with each other outside the boiler, in combination with the blow-off cock L, and the boiler, substantially as and for the purpose described.
